Q & A

Q. I want to use this insert with a rotary dimmer switch. Now do I install it if the screw holes are 2-3/8" apart?
A. Install the device and the strap together with the same screws into the electrical box mounting screw holes spaced 3-9/32" apart. Then when you place a rocker wall plate over it, the screw holes in the plate will align with the screw holes in the far end of the strap at 3-13/16" spacing center to center.
